Answer

Species of the Enterobactercloacae complex are gram-negative bacilli that belong to the Enterobacteriaceae family. Other members of this family include Klebsiella, Escherichia, Citrobacter,Cronobacter, Serratia, Salmonella, and Shigella species, among many others. Enterobacteriaceae are the most common bacterial isolates recovered from clinical specimens. These bacteria have an outer membrane that contains, among other things, lipopolysaccharides from which lipid-A plays a major role in sepsis. Lipid-A, also known as endotoxin, is the major stimulus for the release of cytokines, which are the mediators of systemic inflammation and its complications.
